      More Power and Better Performance. Now you can add Dyno proven gains in power and torque, as well as improve the overall performance of your 2003-2004 Cobra with a Rev X Programmer that includes 2 Bama Custom Tunes. By optimizing the air/fuel ratio, adjusting ignition timing and tweaking variable cam timing, a Bama Performance Custom Tune will squeeze out the extra power Ford left on the table. Curve Gains of 30 RWHP / 35 RWTQ have been seen on bone stock 4.6L Mustangs with a 93 octane tune. Automatic transmissions will see an even greater gain in acceleration and drivability, as the tune also adjusts shift points and firmness.

      Increase Your Mod's Potential. From the factory, Ford programs their vehicles to cater to the needs of the daily driver, not the performance enthusiast who adds aftermarket bolt-on modifications in search of more power. When making performance mods, you will need to re-calibrate the vehicle's computer to realize their full potential.

      Free Tunes for Life! Every customer that purchases a Bama Rev X Tuner is enrolled in the Free Tunes for Life program. Any time that you make additional mods to your vehicle, our team of certified Bama Calibrators will create new tunes for you. Just send us a list of the part or parts you've added and we'll upload your new tune files to the cloud.

      Custom Bama Tunes Specific to your Pony. When you order a tuner, you aren't just getting a tuner – you're getting the tuner and 2 Dyno-tested custom Bama tunes:

      (91-93 Octane) Bama Performance Forced Induction Tune Files are designed for maximum power and reliability while improving the overall driving experience of your Mustang; however, 91 octane or higher is required. Unleaded race fuel can also be used (Stoichiometric points must be supplied).

      Wi-Fi Updates and Cloud Tuning. The Rev X Tuner by SCT is Wi-Fi capable, meaning it will always be up to date. Once setup with your Wi-Fi password, the Rev X will download the latest firmware updates via the internet. Besides firmware updates, your Rev X can also download your custom Bama tune files via the cloud, reducing the hassles of transferring files from your PC to your Rev X device.

      Data Logging and Monitoring. The Rev X Tuner by SCT makes it easy to read the Built-In Data Logging and/or the Real Time Data, so you can view popular sensor data such as EGT, Air/Fuel Ratio or any other 0-5 Volt source. You can even customize the monitoring capability of your Rev X using device's free Livelink software.

      Diagnostics Tool. The Rev X Tuner can also be used as a diagnostic code reader. Save yourself hundreds of dollars each year by reading and clearing your own Diagnostic Trouble Codes (DTCs) rather than paying a dealer to do the same. It's as easy as a few simple steps.

      Easy to Load; Easy to Restore. When you load your custom tune on the vehicle, the tuner automatically stores your vehicle's factory settings. To return the vehicle to its factory settings, just plug the tuner back in, select the option to restore the factory settings and you're done. This is ideal for visiting dealerships for warranty work.

      Application. This Bama Rev-X Tuner by SCT with Custom Tune Files by Bama Performance is specifically designed to fit the 2003-2004 Cobra Mustang. Please note that this programmer is not legal for sale or use in California on pollution controlled motor vehicles.

      **Please Note: The Rev-X Performance Programmer ships blank from AmericanMuscle. Your custom tune files will be available for download via the cloud when your tuner arrives.

      It's highly recommended to download Free LiveLink and Updater Software. The LiveLink Application is used to view, data log, record and playback your Mustang's PCM data on a laptop computer. The Updater Application lets you update your device's Firmware, Tune Revision or to load Custom Tunes onto your device. Requires Windows Vista/7/8/10 and an internet connection.

        5 2003 Cobra - stvenkng

        Quick and easy

        Bama Rev-X Tuner is the easiest tuner I have ever used, plugged in to a power source located my Wi-Fi entered the pass code hooked up and downloaded the two Bama tunes from the "Cloud" no messing around with emails that can get lost or corrupted just "get my tunes" and done. Install is pretty much like any other tuner but there are tuneable features and the SCT Livelink Gen II app that aids in tuning as well as code reading... I prefer the Rev-X over loading more stuff in my Iphone and free tunes for life doesn't hurt either as I have a back room full of go faster stuff for my Terminator in my garage..

        2 2003 Cobra - ErikV

        Not worth the price

        Got one for my 03 Cobra. If it was cheaper it would be a good deal. My car runs decent other than stalling out randomly since the tune, but it won't clear my codes that I have now from deleting parts of my EVAP and EGR system, and apparently they can't take that out of the tune anymore through Bama tunes. I really just use it as an extra gauge now since it can show a few things at the same time. Just get a Dyno tune.
